Application filed November 14,1904. Serial No. 232.651.

' Millbury, in the county of Worcester and State of Massachusetts, have invented certam new and useful improvements in Manure-S readers and I do hereby declare that the fo lowing is a full, clear, and exactdescription thereof, whichwill enable others skilled in the art to which'it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification. One of the ob ects of my present invention I is to provide an improved tail board and op erating -mechanism for manure-spreaders, and'particularly such spreaders as have a 1'0- tary beater and a movable bottom to carry thefertilizer to the beater in discharging.

Figure l of the drawings shows a side elevation of the machine embodying features of my invention. Fig. 2 shows the rear end of the machine in broken-out sec?? on, showing what may-be termed the intermediate or second position of the t-ailboard and its mountings. Fig. 3 shows in a somewhat similar manner the rear end of the machine with the tail-board in open position. Fig. 3 shows details at the forward end of the machine particularly appertaining tothe mechanism for throwing the movable-bot tom feeding mechanism out of gear. Fig. 4 shows a partial sideelevation of the maclnne as seen from the opposite side to that. shown in Fig. '1. details of parts of the'feeding mechanism. Fig. 6 shows a plan view of the same. Figs. 7, 8, and 9 show details of other parts of the feeding mechanism. Fig. 10 shows the rear end-of the machine as seen from the left.

Referring to the reference -figures in a more particular description of the device, 1 indicates the sills of the frame, which, together with the side boards 2 and the movable bottom of slats 3, constitute the load-holding box of the machine. is supported or carried by the rear wheelse, which also serve to drive the mechanism when s reading or discharging the load, and by the forward wheels 5. The bottom 3 corn sists of slats, as common and as more particularly shown in Fig. 2, which are secured to a continuous chain 6, passing around wheels or rollers 7 .on the rear end of the machine Fig. 5 shows, on an enlarged scale,

The box and the wheels or rollers S on the forward 5 end of the machine. The bottom 3 may be supported intermediate of its length by rollers, as 9, arranged on the inner side of the sills l on the flame. The wheels or rollers T, which carry the rear end of the movable bottom, are secured on the shaft 10, having hearings on the frame and extending transversely of the rear end of the frame. At one end the shaft 10 carries the toothed wormwheel 11, which is adapted to be engaged by the worm 12, provided on the rear end of the feeding-shaft 13 The forward end of the feeding-shaft 13 is provided with a bevelgear pinion 14, which meshes with teeth on the farther side of the combination ratchet and gear wheel 15, mounted on a fixed pivot 16 on the frame. On the pivot 16 there is also mounted the two ratchet-levers 17 and 18, having pawls 17 and 18, respectively, adapted to engage with the internal ratchetteeth of the combination ratchet and gear wheel 15. There are provided springs 17 18 as shown, for holding these pawls 17 and 18 in engagement with. the ratchetteeth, while ermitting the same to be retracted over tlhe teeth.

The swinging ends of the ratchet-levers 17 and 18 are connected, respectively, with the rocker '20 by means of the connecting-rods 21 and 22. The rocker is mounted one fixed "pivot 23 on the frame and provided with an adjustablearm .54, sliding freely through an eye or opening on the rocker 20. The end of the arm 2% is connected by a connecting-rod 25 with the driving-crank 26, provided on one end of the shaft 27. The shaft- 27 is provided-at the left-hand side of the machine. with a gear-pinion28, which meshes with a gear-wheel 29, provided on the axle shaftof the rear wheels e. 5 It may be noted that the-axle-shaft 30 is. preferably coupled to the hubs of the wheels 4: by means of an ordinary ratchet connection 31, which serves to turn the shaft when the machine is moved-forwardly, but allows the wheel an independent movement, as when turning the machine around. For adjusting the position of the arms 2a with ref-- erence to the rocker 2G there is provided a lever 35, mounted on a fixed pivot 36 on a frame and connected at one end, by a connecting-rod 37, with the pivot or joint be tween the parts 24. and and at the other whereby when the lead machine will spread 'wardly in a substantially end connected. by a rod 38 with an adjusting lever handle 3!), m'o'vided on the front end of the machine, convenient to the operator. This lever is loosely pivoted. on shaft 72 and is provided with a catch 40, adapted to engage with a fixed rack 41, whereby the lever and its attached. parts may be secured'in any desired position of adjustment.

At the rear end of the machine there is pro vided in the usual manner a rotary beater 50, provided with pins or teeth 51 and mounted on ashaf t 52, supported in suitable fixed bearings at the rear of the machine. The heater is arranged to be rotated in. what might be termed an overshot dircctionthat is to say, in the direction indicated by the arrow in Fi 3. For dr'ving the beater there is provided on the end of the. shaft 52 a sprocket-wheel 53, which is connected by a sprocket-chain 54 the ground at .the rear moved forward, there are provided. su

with the sproehet-wheel 55, secured on the shaft 27, before mentioned.

i or holding the load against escaping to the rear or 'beeomhug-engaged. with the beater in such manner as to practically prevent the beater from getting started w hen it is desired ,to throw the beater into operation there is provided a tail-board 60.. This tail-board is preferably made curved or of a circularferm, so as to present a convex side to the load and a concave side toward the beater, end s mounted on a swinging frame having arms 61, pivoted at 62 to the. bell-crank-lever hangers 63, which lever-hangers are pivoted on f ixed pivots to the frame at 64. The arm of the bell-crank hangers 63, which the beater-arms are not pivoted, extends forhorizontal dire-otion and. has a limited movement between the stop 65, on the one side, and the shoulder 65 on the other side, as quite clea; appears from Figs. 1 and 3 of 'i ii drawings. The hangers 63 also have at their outer ends a shoulder or stop 66, against which the arms 6] are adaptr-id to swing and engage. therewith in holding the taitiioard in its open position. (h nnecting with the arm 61 at an intermediate point and extending forwardly on either side of the box there are provided eonnecting-rdds 70. At their forward ends these rods connect with crank-arn'is 7], provided on a rock-shaft 72, supported in suitable bearings on the front end of the box and adapted to be operated by a lever-handle 73 in convenient position to the operator and on the opposite endof shaft 72 from that on which lever 39 is loosely mounted. The le ver-handle 73"Tis provi ed with a catch 74., engaging with a holding-rack 75, which holding-rack, however, will preferably be provided witlronly two securing-notches, one at the limit of movement in each direction.

'llie curvatnre of the tail-board 60 is preie'ral'i'ly about the same as that of the beater, strikes the beater the or distribute the fertilwith tin on the end of a rock-s teases comes into engagement with-the beater.

The curved form also provides a closer-fitting shield overthe top of the beater when open-position to prevent the fertilizer being thrown by the heater in an upwardly direction or discharged'otherwise than in a shower to, the rear of the. machine.

In order to prevent fertilizer escaping-Ito the sides and to secure a well-defined. in ginal line to'the strip of fertilizer fallin n of the machine a mentary side pieces or end wall-pieces 77} cured to the frame or box, and which )rac I cally closes the ends of the tail-board piece 60 when acting as a shield over the beater. Spanning the rear end of the'Inachinc at a .position close to the tail board and heater there is provided a comb 80, pivotallymounted in brackets 81 and free to swing backwardly or forwardly, but particularly into the position shown in Fig. 3 in engagement rearedge of the tail-board 60 when. inv open position, to which position the bomb 8 will be moved by coming in contact with the distributing of an overful load. This arrangement serves to cause all of the load to pass under the edge of the tail-board 60 acting as a shield, and the comb alsoserves to secure better pulveriaing of the fertilizer as it IS- pcrai.ed upon by the heater in disiiilblllllh -j and discharging it to the rear of the machine.

The rear end of the feeding-shaft 13 is carried in a verticaii movable box 13, which is moved vertical y to throw' the worm 12 into or. out of engagement with. the wormwheel 11 i means of the crank 13", engaging in a slotted opening in the topof the box,and the connecting-rod 12,3",extending to the forward end of the machine. The forward end of rod 13" is provided with a tooth adapted to engage with pin '71 in the crank-arm 71', which is double on that/side of the machine, and an. extension of the rod 13 beyond the tooth extends between the two parts of this arm 7]. The spring 13 serves to move the rod 13 towardthe front and throw out the worm 12 whrnnot otherwise held. When the lever 7'3 is operated to swing the crankarm 71 to the the pin 71, the spring 13" is overcome, and the worm- 12 thrown into 0 ieration. To trip the feeding mechanism and get it out of gear, there. is a trip-lever )0 provided, pivoted at 91 and adapted to engage 13 and force it up to disengage the tooth-from 71'. To operate the trip-lever 90, there is rovided a finger 92 lia'ft -93, extending across the frame and having a projectien94, adapted to be engaged by a slat between the cha ns 6. l

rear, the tooth engages with.

. omitted and attention called simply to certain more particular features.

it will be noted. that when-the adjustable. arm 24' of the rocker is moved to a position to shorten the arm with reference to the distance it projects from the ivet 23 of the rocker the rockerwill have a greater movement. .llencethe ratchet-levers 17 and 1.8 will be moved farther with each revolution of the crank-shaft 27, whereby the movable bottom will be fed to the rear faster and the load ,discharge more rapidly and of course 'distrilnite more thickly over the ground.

As the arm 24 is extended the movement of the ratehet-levers 17 and 1.8 is decreased, and of course the movable bottom isnioved to the rear less rapidly, resulting in a thinner distribution of the-fertilizer over the grotnd. The lever 39 for controlling this adjustment is readily within "the. reach of the operator, whereby he can vary thedistribution, depending uponfthc nature of the ground that the machine is being passed. over and the nature. of the contents of the box which is being distributed.

With reference to thetail-board, when the box is loaded the tail-board will be held in its closed andl'orward position by a continuous draft on the side connecting-rods 70. hen

it is desiredto diselntrge the load, the first movement so far as the tail-board. mechanism is concerned is a thrust movement on the rods 70, which moves the tail-hoard rearwardiy, while the hangers 63 nove froi h the position shown in 'l ig. .1v to thatshown in Fig. 2, In so doing the tail-board is carried away fro n the fertilizer in the box, as shown in Fig. 2. The further thrust iHOVGJ'HGIlt' on the rod 7 0 causes tl 10 frame carrying the tailboard to swing on the ,pivot 62 until it is stopped by coming in'contact with. the stopsho'elder 66, in which position the tail-board will occupy. a positioirover the beater and will be adapted to operate as a shield, as heretofore pointed out. Of course iiunerons other at echanisn'is are provided in eomiection with the machine as, for-instance, u echanisins .to stop the li'lOVG'iPOIlf/Ofbllb bottom when the load has been entirely distributed, &c.-whic h it is not deemed. necessary to specifically describe herein.

Whatl claim as new, and desire to secure: by Letters Patent, is I 1. The combination in a manure-spreader of a load-holding box, a tail-board therefor, mountings forjthe tail-board arranged to pro vide for an initial movement thereof longitn}.
